Tomasi C, et al. - Experts aimed to analyze whether characteristics of the fresh extraction socket site influenced subsequent dimensional alterations and if the placement of deproteinized bovine mineral in the socket affected volumetric change during healing. The overall diminution of the ridge that occurred during healing was not influenced by the graft of collagen-enriched deproteinized bovine bone mineral, placed to fill extraction sockets. An apparently significant influence of the thickness of the buccal bone wall was noted on the edentulous ridge following tooth extraction.
